Title: Improvements relating to the manufacture of refractory magnesia products
Filed: 1934-04-27
Abstract: A refractory magnesia product bonded predominantly by calcium ferrite is made by calcining a mixture providing magnesia, not over 3 per cent of silica, a component rateable as ferric oxide and containing not less than 50 per cent of ferric oxide, and lime in amount sufficient to convert the silica into dicalcium silicate and to provide lime free to combine with the component rateable as ferric oxide in amount which is not less than four tenths of the amount of such component.  The component rateable as ferric oxide may contain oxides of chromium and aluminium, or may be non-siliceous iron ore, or mill scale.  The lime may be added as limestone or dolomite.  The proportion of lime should not exceed seven-tenths of the total ferric oxide component when the latter is all ferric oxide, or eighty-six hundredths when the latter is sixty per cent ferric oxide.  The finished refractory product may contain from 7 to 20 per cent of calcium ferrite.  Three analyses are given of clinkers made by this process, in which the silica amounts to from 1,2 to 2,2 per cent, the component rateable as ferric oxide (which in these three cases includes aluminia) from 4,7 to 9,7 per cent, and the lime from 5,5 to 10,4 per cent.  Specification 394,115 is referred to.

Title: Improvement in methods of surface lubrication of metal products
IPC: C25D5/48
Filed: 1944-07-05
Abstract: The surface of metal products, e.g., sheet tin plate, is coated with lubricant by depositing thereon a lubricant in water emulsion containing an emulsifying agent of sufficient concentration to stabilise the emulsion but insufficient to prevent adhesion of the lubricant, washing the emulsion with water to remove substantially all ingredients thereof except the lubricant and drying the product. Suitable lubricants comprise palm oil, cotton seed oil, corn oil, lard oil or plasticisers such as dibutyl phthalate and tributyl citrate and emulsifying agents comprise ammonium hydroxide, triethanolamine stearate or <PICT:0594076/III/1> oleate, 1- aminoethyl- 2- heptadecenyl glyoxaldine, or mannitan monopalmitate or n-dodecyl amine.  The emulsion may be acid, alkaline or neutral and wetting agents such as turpentine or pine-oil, water insoluble aliphatic alcohols, long chain aliphatic carboxylic acids such as 9-octadecenoic acid may be used.  As shown the emulsion 13 passes through a homogenizer 12 and reaches the continuously moving metal strip 5 through low pressure sprays 7.  Water is supplied through sprays 8 and the lubricant is dried by steam coils 11.

Title: Improvements in or relating to shock absorbers
IPC: F16F9/22
Filed: 1933-05-03
Abstract: 402,338. Hydraulic shock-absorbers. DELCO PRODUCTS CORPORATION, 329, Dast 1st Street, Dayton, Ohio, U.S.A.-(Assignees of Funston, F. D.; 1908, North Main Street, Eayton, Ohio, U.S.A.) May 3, 1933, No. 12924. Convention date, Jan. 25. [Class 108 (iii).] In a vehicle hydraulic shockabsorber comprising a piston 37 reciprocating, under vehicle spring movements, in a cylinder 25, (a) on slight rebound of the vehicle spring the piston is moved to the right, Fig. 2, and forces fluid through an outlet port 39, a bore 71 in a spring-pressed sleeve-valve 64, a side-passa,ge 62 in a fixed tubular member 57, and an annular groove 85 in an external sleevevalve 80, to a reservoir 24 ; (b) on greater rebound the valve 64 is moved from its seating 63 so that fluid also flows to the reservoir through an annular groove 76 in the valve and through passages 61, 83 in the member 57 and valve 80 respectively ; (c) on further increased rebound a pressure release valve 49 in the pistonhead is also opened ; and (d) on sufficiently great rebound of the vehicle springs an inertiacontrolled mass 100 moves the sleeve-valve 80 relatively upwards to close the passage 62, the resulting pressure above the valve 64 causing it to re-engage its seating 63 thus shutting off the groove 76 and passages 61, 83 so that fluid escapes only past the valve 49. On compression of the vehicle springs the piston 37 moves to the left under the action of the spring 45 and the spring-pressed valve 42 opens permitting substantially free flow of fluid through the piston. The mass 100 is maintained in its normal balanced position by an adjustable spring 102 and is secured to one end of a bracket 91 pivotally carried by a pin 92 fixed to the casing 23, the other forked end of the bracket abutting a flange 87 on the valve 80. The passage 62 causes fluid pressure on one side only of the valve 86 which tends to maintain the valve in the closed position as long as pressure is maintained in the chamber 75. The lower end of the valve 64 is cut away so that the fluid passing through the bore 71 forces the valve to one side to prevent chattering.

Title: Improvements in and relating to the Reading of Contaminants in Fluent Materials.
Inventor: DEHRIE JILL
IPC: G01N15/06
Filed: 1967-03-20
Abstract: 1,181,565. Photo-electric inspection of filter tapes. E.K. VON BRAND. March 20, 1967 [April 6, 1966], No. 12982/67. Heading G1A. A contaminated fluid or fluidized material is filtered through a continuously moving filter tape which is photo-electrically inspected whilst exposed to the fluid or fluidized material. The tape may be treated chemically to react with the contaminant and so become discoloured or the fluid or fluidized material may be treated chemically to discolour the contaminant before it is deposited upon the tape. However the contaminant may be naturally coloured sufficiently to discolour the tape upon deposition, e.g. soot in air or burner exhaust gases. In these cases where the tape is discoloured it is inspected by a light sensitive cell, but if a radio-active contaminant is collected either a geiger-counter is used instead of the cell or the tape must be sensitive to radio-active contaminant. The tape may be further photo-electrically inspected subsequent to exposure to the fluid or fluidized material. In the arrangement shown in Fig. 1 contaminated gas enters via tube 46 a chamber 16 in an upper block 12, flows through a continuously moving filter tape 48 into a chamber 18 in a lower block 14 and exhausts via tube 40. Embedded in the blocks 12 and 14 are metal inserts 50 and 52 which define by matching holes 36, 38 the area of the tape exposed to the gas, and may be replaced by others with different sized holes. Lamp 70 illuminates this area and light is diffusely reflected on to one or more rectangular photo-cells 88 or alternatively on to an annular photo-cell surrounding the aperture 86. The optical housing 60 rests upon the upper block 12 to which light enters via a window 58. Although not shown a second vertical passage way may be provided in the upper block via which a second photo-electric arrangement may view the tape subsequent to exposure.

Patent GB-806660-A (GB)
Title: Chloroform extraction process for improving recovery of adipic acid
Filed: 1956-04-30
Abstract: Adipic acid is recovered from its crude aqueous solution produced by the liquid phase oxidation of cyclohexane or a primary oxidation product thereof with molecular oxygen and extraction of the oxidate with water, the aqueous adipic acid solution containing other non-volatile products formed in the oxidation which tend to keep the adipic acid in solution and interfere with the crystallization of adipic acid therefrom, by extracting the crude aqueous adipic acid solution with chloroform whereby amounts of the crystallization-interfering nonvolatile products are removed and then crystallizing adipic acid from the so-purified aqueous solution.  The extraction with chloroform is preferably carried out at 45-49 DEG  C. and counter-currently in a series of extractors; the aqueous extract preferably contains more than 40 per cent of water.  The chloroform extract is water-washed and the washings and treated aqueous adipic acid are combined, concentrated down and then crystallized, preferably using a series of crystallizers, the end vessels being at a lower temperature. The method may be used in the oxidation of cyclohexane to cyclohexanol and cyclohexane with molecular oxygen at 50-175 DEG  C. under a pressure of 50-250 lbs./sq. inch using, preferably, as catalyst, a cobalt salt such as the naphthenate and treating the oxidate with water.  The aqueous extract of adipic acid may be used directly in the chloroform extraction or after removal of unchanged cyclohexane and, if desired, the minor amounts of cyclohexanol and cyclohexane present and some of the water.  The oxidation and recovery of the aqueous oxidate extract, including stripping of cyclohexanol and cyclohexanone therefrom and their further oxidation with nitric acid may be effected as described in Specification 767,348.  The recovery method may also be used in processes in which adipic acid is the primary cyclohexane oxidation product or wherein the cyclohexanol and cyclohexanone are obtained as described above, the cyclohexanol is dehydrogenated to the ketone and the total cyclohexanone is then oxidized to adipic acid, as described in Specification 566,110, [Group IV].  Also, the above-mentioned aqueous adipic acid extracts may be combined with adipic acid mixtures from other sources and then subjected to the recovery method.  In an example, cyclohexane is partially air-oxidized at 145-155 DEG  C. under 130 lbs./sq. inch pressure using cobalt naphthenate as catalyst; the oxidate is treated with water and the aqueous extract is stripped of steam volatiles and then subjected to the above chloroform extraction and crystallization procedure.
